How to Judge a Builder's Track Record
Picking the right builder means looking at real numbers and asking the right questions. Here are the key things to check.

A high project count shows deep experience. Builders who have finished many ADUs have strong supplier ties and know how to solve problems fast. Look for builders with 20 or more completed detached ADUs.
When reviewing a portfolio, note:
- Variety of sizes and styles
- Projects in different LA neighborhoods
- Mix of build types (garage conversion, backyard, custom)
Permit Approval Rate
This tells you how often a builder's plans pass review on the first try. Good builders score above 85%. The best exceed 95%. New Dawn Construction has a 97% first-try approval rate.
A high rate means:
- Fewer delays from plan rejections
- Strong ties with city plan reviewers
